James Hansen planetary emergency 2008 short VIDEO
In 2008 and again in 2012 James Hansen made a public statement warning that as a result of the rapid Arctic changes a planetary emergency existed. In 2010 James Hansen's book Storms of My Grandchildren The Truth About the Coming Climate Catastrophe and Our Last Chance to Save Humanity explained the emergency in detail.
In 2009 Lester Brown, an American leading expert in sustainability published his Plan B 4 (Earth Policy Institute) Mobilizing to Save Civilization. His plan to deal with this unprecedented crisis is the most comprehensive there is.
Many authorities have warned that we are in a global climate change planetary emergency.
The rapidly melting Arctic snow and summer sea ice has already changed our world. Now the Global North is in a climate emergency situation as well as the Global South, due to N. hemisphere climate instability, extreme summer heat and drought. This will first affect world food security and prices hurting billions of most vulnerable people in the world.
Many food producing regions have been affected by drought in the past few years.
In addition a planetary emergency exists for all future life because the Arctic summer sea ice is past its tipping point (2007) and Arctic methane feedback has started, which leads to rapid runaway global warming.
Scientists Consensus on Maintaining Humanity's Support Systems MAHB May 2013
World Bank Turn Down the Heat reports 2013. The world is being committed to an end of the world 4C warming. A 2C world (the 2C target) is catastrophic for billions. ' ...the science is clear. There can be no substitute for aggressive national mitigation targets, and the burden of emissions reductions lies with a few large economies.”
The rapidity with which the human-caused positive forcing is being introduced has no known analog in Earth's history. (J. Hansen )
